Portulaca plant named ‘DPORPZNYLW’

ABSTRACT

A new and distinct cultivar of Portulaca plant named ‘DPORPZNYLW’ is disclosed, characterized by large, bright yellow flowers on semi-upright, compact plants. Blooming begins early. The new variety is a Portulaca, normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Portulaca oleraea.

Variety denomination: ‘DPORPZNYLW’.

BACKGROUND OF THE INVENTION

The new Portulaca cultivar is a product of a planned breeding program by the inventor, Gavirel Danziger, at a commercial greenhouse in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Portulaca varieties. The open pollination resulting in this new variety was made during October of 2014.

The seed parent is the unpatented, propriety variety referred to as Portulaca ‘PT-14-1152’. The pollen parent is unknown. The new variety was discovered in June of 2015 by the inventor in a group of seedlings resulting from the open pollination, in a greenhouse in Moshav Mishmar Hashiva, Israel. Date of first sale was Nov. 5, 2017, in Hungary. This sale was made directly by the inventor or one who obtained the claimed invention directly or indirectly from the inventor. This sale and all public disclosures made between Apr. 1, 2018 and the filing of this application fall within the exception allowed under 102(b)(1).

Asexual reproduction of the new cultivar ‘DPORPZNYLW’ was first performed by terminal vegetative cuttings during August of 2015, at a greenhouse in Moshav Mishmar Hashiva, Israel. Subsequent propagation by has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DPORPZNYLW’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DPORPZNYLW’ These characteristics in combination distinguish ‘DPORPZNYLW’ as a new and distinct Portulaca cultivar:

-   1. Semi-upright and compact habit. -   2. Big bright yellow flowers. -   3. Long blooming period—from Spring to Autumn. -   4. Freely branching habit. -   5. Early flowering.

PARENT COMPARISON

Plants of the new cultivar ‘DPORPZNYLW’ are similar to plants of the seed parent in most horticultural characteristics, however, plants of the new cultivar ‘DPORPZNYLW’ differ in the following;

-   1. ‘DPORPZNYLW’ has a very compact habit comparing to ‘PT-14-1152’. -   2. ‘DPORPZNYLW’ is open and flat. ‘PT-14-1152’ is conic     (funnel-shaped). -   3. Flowers of ‘DPORPZNYLW’ are larger than flowers of ‘PT-14-1152’. -   4. Flowers of ‘DPORPZNYLW’ are yellow, while flowers of ‘PT-14-1152’     are orange.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DPORPZNYLW’ can be compared to the unpatented commercial variety Portulaca ‘DPAZYLWIMP’. These varieties are similar in most horticultural characteristics; however, ‘DPORPZNYLW’ differs in the following:

-   1. ‘DPORPZNYLW’ has more compact and dense habit compared to     ‘DPAZYLWIMP’ -   2. ‘DPORPZNYLW’ has bigger foliage than ‘DPAZYLWIMP’.

Plants of the new cultivar ‘DPORPZNYLW’ can also be compared to the unpatented commercial variety Portulaca ‘DPAZVIVIDY’. These varieties are similar in most horticultural characteristics; however, ‘DPORPZNYLW’ differs in the following:

-   1. ‘DPORPZNYLW’ has a brighter yellow flower color compared to     ‘DPAZVIVIDY’. -   2. ‘DPORPZNYLW’ has more compact and dense habit compared to     ‘DPAZVIVIDY’ -   3. ‘DPORPZNYLW’ has larger flowers than ‘DPAZVIVIDY’. -   4. ‘DPORPZNYLW’ has brighter foliage compared to ‘DPAZVIVIDY’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DPORPZNYLW’ grown in a greenhouse in Moshav Mishmar Hashiva, Israel, in a 20 cm basket. Age of the plant photographed is approximately 20 weeks from a rooted cutting.

FIG. 2 illustrates a close up of the foliage and flowers.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
